terminate eating if pet falls asleep or becomes paralyzed (trunk only)

     From a bug report:  sleeping pet could
be shown as "eating" by stethoscope.  Fixing that is a one-liner since all
(or should be all; sleeping gas trap wasn't utilizing it) cases of monster
being forced into sleep go through one routine.  That wasn't the situation
for paralysis, but now it is.  Paralyzed pets won't continue eating either.
